BISSELL, a citizen of the United States, residin r at Bay City, inthe county of Bay and State of Michigan, have invented a new and usefulImprovement in Wave Mo tors, of which the I from. The upper end of thetank is arranged following is a specification. above the normal crestline of the waves and This invention relates generally to Wave I theopen end of the tank is arranged below motors and more particularly toone in which the rise and fall of the water in wave motion I 111g motionor producing power. th The object of my invention is to construct l awave motor operating upon this principle, which shall be exceedinglysimple and durable and highly effieient in operation.

Another object of the invention is to so construct the wave motor thatnot only the which is approximately the wei ht of said water, risingwithin the tank. T e air thus forced from the tank is introduced into amotor H and l the said air acting upon this motor will drive mechanicalmotor but the exhaustive force the same in a manner well known in theoputilized upon the opposite side thereof. eration of compressed airmotors, and the Another object of the invention is to propipe I whichleads from exhaust end of the vide suitable safety appliances for thepurmotor is carried back into the tank A adjacent the upper end of thesame and dispose of preventing cho ing and supplying charges the airwhich passes through the thetank with all needed air.

In order to guard against undue compres- Si n and a consequent chokingof the ap al ratus, I provide an upwardly opening re of valve L, in thepi )e 1, between the motor and tank, said va ve discharging mto theouter air so that if because of the still rising wave in the tank or forany other reason the valve K should fail to operate this valve L openingand discharging into the air would permit the apparatus to continue itsoperation and if for any reason the air supply in the tank should becomeso exhausted as to require additionalair, I provide for the same byinterposing'a valve chest M, between the I valve E and motor H andarrange an inwardly opening valve N, so that if addiuickly needed in thetank A, this valve will open as soon as the driven air in the pi e G, isovercome by the suction of the pipe l, and the air will rush in and passIt will thus be seen that I effectively provide against undue comression and exhaustion.

While I lave shown the tank A as rigidly secured to the standards B itis obvious that this tank can be made adjustable in order to accommodatethe tank to the height of the water at high and low tide if such acondition be desired.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent, is:- I

1. A wave motor comprising a tank open at the bottom, closed at the top,the upper end of the tank being provided with an outwardly openingvalve, an air pipe leading from the said upper end of the tank and areturn pipe leading into the tank adjacent its upper end aninwardly-opening valve arranged at the inner end of said return pipemeans for admitting additional air, and means for liberating air fromsaid air pipes.

2. A wave motor comprising a tank open at the bottom, closed at the top,said top having an outwardly opening valve, a pipe leading from-saidupper'end, a motor into 1 which said pipe leads, an exhaust pipe leadingfrom the motor back to the air tank at a oint adjacent the upper end, arelief valve in said pipe and an inwardly o iening valve arranged at theinner end to sai return pipe.

3. A wave motor comprisinga tank open at the bottom and closed at thetop, said tank being so arranged that its upper end is above the normalcrest line of the wave, and its lower end below the normal trough lineof the wave, the top of the tank having an outwardly opening valve, anair 'pipe leading from said upper end, a valve therem, a motor intowhich the said pipe leads, an exhaust pipe leading from the motor backinto the air tank at a point adjacent the upper end of said tank, arelief valve in said )ipe and an inwardly opening valve arranged at theend of said pipe.

4. A wave motor comprising a tank open at the bottom, closed at the topand having an outwardly opening valve, an air pipe leading from saidupper end, a motor to which the said pipe leads, a return pipe leadingfrom the motor to the air tank and having an inwardly opening valve,'atits inner end, a safety outlet valve arranged between the motor and tankand an emergency inlet valve arranged between the tank and motor as setforth.

5. A device of the kind described consisting of a downwardly open tankpartially submerged, an air pipe, said air pipe having communication ateach end with said tank, an air motor arranged in said air pipe, meansfor admitting additional air other than that inthe tank to said airpipes, means for liberating surplus air from said pipes, air beingforced through said air motor upon rise the tank and sucked through themotor upon fall of water in the tank, the air passing of water in 7through the motor at all times in onedirec-
